Vented guardrail for stoves



May19, 1953 D. P. O'KEEFE VENTED GUARDRAIL FOR sTovEs Filed May 2, 1949 IN VEN TOR.

Azzo r99 65 to the other. the top 21 is substantially flat and is horizontally disposedJ However, it is to be observed that the end portions of the top are slightly pitched and finally curved or flared into the ends 26 to'provide a smooth, rounded construction free of sharp or objectionable corners. A feature of the pres- 7 the drawings is rectangular 3 with doors 18 which provide communication to cooking compartments provided within the body. In the particular case illustrated the stove S has two cooking compartments each of which is provided at its upper rear corner with a vent opening 20 and the stove has vertically disposed flues 2| at the back l3 coupled with the vent openings 20 by suitable fittings 22 so that air flowing into the lower ends of the flues 2| flows upwardly and mingles with gases, fumes, or products of combustion issuing from the cooking compartments to the end that a mixture of air and such products is delivered to the upper end of each of the flues.-

tion is preferably constructed as a unitary ele-' ment applicableto the. upper rear corner of the stove body to extendacross the stove at the back thereof and to project upwardly from the top III, as clearly shown in the drawings. The guard rail construction provided by the present invention is characterized, generally, by a fiat substantially vertical front wall 25, end walls 26 that extend or project rearwardly from the ends of the wall'25, a substantially flat horizontally disposed top 21, a bottom 28, and one or more ducts 29.

In accordance with the preferred form of the invention the front wall of the guard rail is recessed at its lower edge portion so that it presents a downwardly facing shoulder 3|] to seat upon the rear edge portion of the stove body and a forwardly facing vertical wall portion 3| depending from the rear edge of the shoulder 30 to bear against the back l3 of the stove adjacent the upper rear corner thereof, all as clearly illustrated in Fig. '7 of the drawings. When the guard rail is constructed as just described the parts that have just been referred to may be utilized in securing the guard rail to the body of the stove. For instance, suitable releasable fasteners such as screw fasteners may be employed to join the shoulder 30 with the body of the stove.

In the preferred form of the invention the guard rail G is made coextensive with the stove,

that is, so that it extends from one end l2 to the I other of the stove, in which case the front wall 25 of the guard rail may be made aflat continuous element that extends throughout the length of the guard rail, as shown in the drawings. In practice it is generally desirable to construct the guard rail to accommodate elements such as instruments 38 or the like, in which case one or more portions 39 of the wall 25 may be provided toform instrument panels. In the particular case. illustrated there are two instruments 38, both located at a single instrument panel 39, and the portion of the front wall 25 forming the in,- strument panel is located midway between the ends of the Wall 25. According to the present invention the panel portion 39 of wall 25 is rearwardly ofiset from-the plane of the front wall and is inclined upwardly and rearwardly somewhat from the plane of the wall 25 so that it extends upwardly and rearwardly as clearly illustrated in Fig. 6 of the drawings.

The top 2! of the guard rail is located above so that it extendsfrom one end of the guard rail In the particular case illustrated for overlies the upper edge portion of the front wall 25 and is preferably coextensive therewith ent invention is that throughout a substantial portion of its length the top 21 not only projects rearwardly a substantial distance from the vertical plane of the front wall 25, but it also projects forward therefrom. 1 In the particular case illustrated the middle portion 40 of the top 21, which portion extends a substantial distance in either direction from the instrument panel 39, extends forward from the wall 25 and this forwardly projecting part of the top 21 carries a depending lip 4| which extends downwardly to a point opposite and forward of the upper edge of the instrument panel 39 and the upper edge of the wall 25 as it extends in either direction from the instrument panel. The forwardly projecting portion 40 of the top 2! with its depending lip 4| defines an overhanging forwardly projecting part having an opening or chamber 45 to accommodate elements of construction as will be hereinafter described. In practice the space that occurs between the lower edge of the lip 4| and the upper edge of the instrument panel and wall 25 may be spanned or bridged by a connecting part, although in the form of the invention illustrated there is no such part except for the portions of the ducts 29, as will be hereinafter de scribed.

' It is to be understood, of course, that the various parts or edges involved, such as the lower edge of the lip 4|, may be inwardly turned as at 46 so that the structure has a smooth neat finished appearance.

The bottom 28 of the guard rail is of limited extent and extends rearwardly somewhat from the lower edge of the depending part 3| and at its rear edge it has an upwardly turned stiffening flange 48. It will be apparent from the drawings how the various parts of the guard rail may be drawn. passed, or otherwise formed from a single sheet of material or may be suitably fabricated so that they are, in effect, a continuous sheet and it will be understood how various ornamental features or elements of design may be incorporated in the construction as circumstances may require.

In accordance with the present invention the opening or chamber 45 occurring in the upper overhanging construction above described ac commodates a lamp 50, which lamp is preferably located immediately above the instrument panel 39 so that when the lamp is on the instruments 38 are effectively illuminated. The lamp 50 may be'confined beneath the top portion 40 and lip portion 4| so that it is concealed.

In accordance with the present invention the guard rail includes one or more ducts 29 serving to handle flow from iiues 2|, of the stove S. In the particular case illustrated the stove has two flues 2| which flues are located somewhat inward from the ends ll of the stove and are confined to the back of the stove and each of the flues opens upwardly at a point a short distance below the top of the stove. Under this circumstance the guard rail is provided with two like ducts 29 and the ducts are located to properly cooperate with the vents 2|.

Each duct 29 is a simple tubular element with a vertically disposed body or shaft portion 60 and a curved or arcuate head 6| projecting from the upper end of the shaft portion. The shaft portion 60 is spaced rearwardly from the front 'wall' 25 so there is ample circulation of air around it. The particular duct illustrated in cross sectional configuration to conformiin shape with theupper end of the stov'e vent with which it cooperates; and this shape continueszthroughout the entire length of the duct i The lower end of the shaft portion 80 of the duct is opened and occurs in the vicinity of the: bottom 28' of the guard railv and when the structure is assembled, as shownin the drawings, the lower end portion of the: shaft. cooperates with. the upper endof the flue 21' so that flow from the flue is. deliveredv into the duct. In the. case illustrated the lower end portion. of the shaft 60' is: flared or. belied, -as.-.at. 62,130 receive theupper. end of the flue 2!. #The headportion. :61 of the duct is preferably. a smoothly curved or arcuate portion of the duct and extends. upward and'forward and then forward and downward, and this portion of the duct is-so proportioned and related to the other parts of the. guard rail as to terminate-between the lower edge portion of the: lip "4t and the upper edge portion of wall v25 at a point spacedifr-om: the instrument; panel 39. In practice "it-is desirable that the discharge end of the head 61: oftheduct be fixed or made fast to the lip-M1 andthe wall 25 where it terminates at these parts. ;In the caseillustrated the duct is not only joined to the lower edge-portion of the lip, as at 10,. and 'to' the upper" edgeof wall 25' at H, but it is held by clips 12 and 13.. V l From the foregoing description it will be apparen-t-thatflow from the lines 21 of the stove is's'o receivedby the ducts as to be conducted upwardly in or through the guard rail to be finally discharged at the front of the guard rail and downwardly, 2 It is to be observed that by spacing of the outlet ends of the ductheads Bi from the instrument panel 39 the instruments 38-at the panel 39 are notsubject to becoming dirty or overheated. Through the novel. arrangement and relationship of parts provided by the presentinvention the ducts 29' not onlydi'sch'arge in a most advantageousmanner but the outle-t openings are substantially concealed from view so that a person working at the stove-doesnot see the ducts. The ducts by discharging downward and somewhat forward as will be apparent from an examination of Fig. of the drawings, distribute the flow at the front of the guard rail so that" there is" no undesirable concentration of heat and the stove may be operated without danger of overheating a wall W againstwhich the structure is arranged and there is no discoloration of the wall or other parts. In practice the exposed 'or visible parts of the guard rail may be formed of baked-enamel or the like so that these parts can be kept clean by merely wiping them in the course of the usual care of the stove. i I
